With the conclusion of practice Thursday, the Chiefs began to wind down what Todd Haley called the toughest week of the season. The Chiefs today will have their usual day-before-a-game walkthrough and Saturday play their third preseason game against Seattle at Arrowhead Stadium. &ldquo;It was week four of hitting each other twice a day most days, it&rsquo;s hot, they&rsquo;re getting tired of seeing the same guys, there&rsquo;s anxiety over jobs,&rdquo; Haley said. &ldquo;But I&rsquo;m looking for guys with staying power, guys that can sustain. That&rsquo;s why camp has to be a tough camp, to decipher or find out who those individuals are. And I think we&rsquo;re starting to find that out.&rdquo;
